STRAW-STA CKER.

SPECIFICATION forming part of Letters Patent No. 484,427, dated October18, 1892.

Application filed October 8, 1891;

To all whom it may concern:

Be it known that I, MARTIN HEINEKE, of Springfield, in the county ofSangamon and State of Illinois, have invented certain new and usefulImprovements in Straw-Stackers,

of which the following is a specification.

This invention relates to mechanism for giving the carrier-framehorizontal oscillation and depositing the straw in an arc of a circle.

It consists in the details of construction and combinations of partshereinafter set forth and claimed.

In the drawings accompanying and forming a part of this specification,Figure 1 is a side elevation of a stacker embodying my invenplan ofcertain details of the oscillating mech- I anism.

Frame 1 is mounted on Wheels for convenient transportation, and isprovided with circular track or Way 3. Frame 2 is mounted on track 3 andhas the partly-toothed wheel 4, concentric with such track. A standard 5is supported from each rear corner of frame 2 and is provided each witha pulley 6 at its upper end. Ways 7 are secured to the front edges ofthe standards, and blocks 8, carrying rollers 9, are adapted to movevertically on the ways. Cables 10 connect with the blocks, run overpulleys 6, and are secured to shaft 11. A worm-wheel 12 is fixed on anend of the shaft. A worm 13 meshes with the wormwheel, and crank 14provides means for rotating the worm and so raising or lowering theblocks 8. Frame 15 is connected pivotally with the front end of frame 2and with the front or lower end of the straw-carrier frame 16. Thecarrier-frame is trussed from below by means of bars 16 and 16, togetherwith king post or brace 16 and the bars, in addition to strengtheningthe frame, are of utility in the operation of raising and lowering thesame. A pair of draw-bars 17 are placed on opposite sides of thecarrier-frame $erial No, 408,090. (No model.)

and are connected pivotally with such frame and with frame 2. Theconnection with frame 2 is at the base of standards 5, and theconnection with the carrier-frame is somewhat to the rear of the pivotalconjunction of the carrier-frame with'frame 15. As a result of thisarrangement the carrier-frame cannot swing upward with frame 15 for apivot without raising the swinging ends of the drawbars and socompelling the forward end of the carrier to move rearwardly over thecenter of the supporting-platform and compensate for the change ofweight on the rear end, which is caused by raising the carrier. In otherwords, the carrier as a whole is balanced with reasonable accuracy onthe turn-table; but when the rear end of the carrier-frame is raised itof course swings toward the turn-table and disturbs the eqnipoise. Thisdisturbance is compensated for or neutralized by the .action of thedraw-bars, which force the forward end of the carrier rearwardly as therear end is raised. So, also, when the carrier-frame is lowered, as seenin Fig. 1, as soon as the descent of the rear end of the carrier isarrested the forward end is held against further descent by thedraw-bars acting in conjunction with the relatively-oblique frame 15. Inoperating this part of the device the crank 14: is turned, thuselevating the blocks 8. The rollers 9 bear against bars 16 and force therear end of the carrier upward, with the result as to self-adjustingequipoise heretofore explained.

Referring to the oscillating mechanism, 18 is the main shaft, and 19 adrive-pulley therefor.

20 is a double or two-end clutch splined on the main shaft.

21 and 22 are pinions mounted loosely on the shaft on opposite sides ofthe clutch and having each a clutch member opposed to and adapted tomesh with the clutch aforesaid.

23 is a gear-wheel meshing with both pin- 1ons.

24: is a worm on the same shaft as the gearwheel.

25 is a Worm-wheel driven by the Worm.

27 is the shaft of the worm-wheel, and 26 is a pinion on such shaft,meshing with wheel 4 of frame 2.

The mechanism just specified enables the motion of the main" shaft to beapplied to the wheel of the oscillating frame',,-the direction of themotion depending on which pinion 21 or 22the clutch engages. This isdetermined by mechanism automatically operated, which will now beexplained and which comprises this feature ofmy inventioni Toothed wheel28 is provided with a tripfinger 29, which extends inwardly beyondtheperiphery of wheel 4. A spring 36 tends to hold the finger in theposition shown in Fig. 3, while permitting it to-move in eitherdirection. Pins 31 and 32 on wheel 28 are adapted to be alternatelyacted on by the finger, thus imparting the motion of the finger to theWheeL- Pins, as 39; ex-t'end through lugs suitabl y placed on wheel 4and atpropee inter valstrip the fihger'29L Wheel 34 is fixed on shaft:38' and provided witlil te'eth which mesh Witli tlie" teeth on wheel 28!The diameter of wheel-3et is-abont one-halt that at wheel 28,- in orderthat comparatively small moticn of the" tripfinger may m ve the; wheel34sa considera-ble distanceon its pivotr Arm a slbtted' heart in which anook bloek' 36 is ad jnsted with relation to the" ivot-by means ofiscrew 36; A trip-lever 37 pi vots looselyon shaft 33 and has a forked--end which loosely engages an aminiar groove: in the An extensionspringz'. er, a
